Playback magazine has talked with Montreal’s Meteor Studios, which is creating 250 shots for Zack Snyder’s 300 adaptation. Here’s a clip from the article:

Most of the shots involve a pivotal nighttime battle between the Spartans and a phalanx of elite soldiers known as the Immortals. Meteor is also working on some daytime scenes set in Sparta itself, involving 3D extensions of the city.

But its big scene is the fight, which also requires a coastal road, a narrow mountain pass and the Aegean Sea. Meteor will deliver by the end of June.
